As California welcomed William and Kate, their friends David and Victoria Beckham welcomed a new addition to their family.
"[The Beckhams] are delighted to announce the birth of their daughter," David's spokesman Simon Oliveira tweeted on Sunday.
The couple's first girl named Harper Seven was born Sunday morning at Cedars-Sinai Medical Center in Los Angeles, weighing 7 lbs., 10 oz.
"Victoria is doing really well and [Harper's] brothers are delighted to have a baby sister," David posted to his Facebook page on Sunday.
This is the couple's fourth child together.
